P3 vs. Anthlon, The AMD can outrun the P3 by just a little on render tims. BUT, it runs very hot. I've had a lot more warranty work on the Anthlon systems than the P3's. If a fan fails it will cook the CPU. If you go AMD be sure to get a MB that has Hardware monitoring and fans that have the RPM detector in them. The P3 is definately more stable. I've seen them run for who knows how long with no fan and still live. Personal opinion on RAM, I'd rather have 512MB of SDRAM than 128 of RAMBUS, about the same price.
